  • If the match ends in a walkover, resolve to 50-50 or 'No' as appropriate

Edge cases & clarifications:

  • Retirement During Match: If one player retires during the match, the market resolves to the player who advances due to the retirement
  • Walkover: If a player withdraws before the match starts, the market resolves to 50-50 or 'No' as appropriate
  • Delay Beyond 7 Days: If the match is delayed beyond 7 days from the scheduled date without a winner determined, the market resolves to 50-50 or 'No' as appropriate
Timing: Resolution occurs immediately after the official WTA Tour statistics and event records are published, or within 2 hours after the event's conclusion if official data is delayed, using credible reporting as a backupOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.

It displays current probabilities, volume of $1,568,417, and 24-hour volume of $1,557,641 across platforms.

Prediction market odds on this market often reflect sharper, crowd-sourced insights compared to traditional sportsbook lines. While sportsbooks incorporate expert analysis and may include adjustments for betting patterns, prediction markets let participants bet directly on their own research. The resulting prices can therefore show different implied probabilities, especially when recent form or surprise factors influence trader behavior. Comparing both can reveal where public sentiment diverges from institutional forecasts.

On Polymarket, this market is priced through continuous trading where liquidity and trader sentiment shape odds. On Limitless, the market may reflect different liquidity conditions or user bases. Polymarket and Limitless can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. For the Kostyuk vs Swiatek match market, factors like recent form, head-to-head history, and betting trends can cause divergence. When one platform has deeper liquidity, its prices often stabilize closer to broader market consensus, while thinner markets might show wider swings based on smaller trades. This dynamic is normal across prediction platforms and helps highlight where trader confidence lies ahead of the match.

Injuries, weather delays, or last-minute player withdrawals could shift this market significantly. Strong pre-match practice performances, betting volume spikes, or commentary from coaches and analysts may also sway trader sentiment. As the match nears, any update that changes the perceived advantage between competitors can cause rapid price adjustments, reflecting evolving expectations among participants on each platform.
